The P0105 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Manifold Absolute Pressure (MAP) sensor or the Barometric Pressure (BARO) sensor circuit. This code is triggered when the vehicle’s Powertrain Control Module (PCM) detects an inconsistency in the readings from these sensors, which are crucial for managing engine performance …
The P0054 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Heated Oxygen Sensor (HO2S) heater resistance, specifically for Bank 1 Sensor 2. This code is part of the On-Board Diagnostics II (OBD-II) system and is triggered when the Powertrain Control Module (PCM) detects an abnormal resistance in the heater …
The P0965 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Pressure Control Solenoid ‘B’ Control Circuit Range/Performance. This code is specific to vehicles equipped with an automatic transmission and is part of the OBD-II system, which monitors various components to ensure optimal performance. When the powertrain control module (PCM) …
The P2243 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor reference voltage circuit, specifically for Bank 1 Sensor 1. This code is part of the OBD-II system, which monitors various components of a vehicle’s engine and emissions systems. When the Powertrain Control Module (PCM) detects an open …
The P1237 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the fuel pump secondary circuit. This code is primarily associated with the Fuel Pump Driver Module (FPDM), which is responsible for controlling the operation of the fuel pump based on the engine’s demands. When the FPDM detects an issue within …
The P0633 diagnostic trouble code (DTC) signifies an issue with the vehicle’s immobilizer system, specifically indicating that the immobilizer key has not been programmed into the Engine Control Module (ECM) or Powertrain Control Module (PCM). This code typically arises when the vehicle’s computer fails to recognize the key being used, which can prevent the engine …
The P0310 trouble code is a diagnostic trouble code (DTC) that indicates a misfire detected in cylinder 10 of an engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various vehicle components to ensure optimal performance and emissions control. When the Engine Control Module (ECM) detects that cylinder 10 is …
The P0271 code is a diagnostic trouble code (DTC) that indicates a problem with the fuel injector circuit for cylinder 4 in a vehicle’s engine. Specifically, it means that the powertrain control module (PCM) has detected a higher than expected voltage in the injector control circuit for this cylinder. This code can lead to various …
The P0472 trouble code indicates a malfunction in the exhaust pressure sensor circuit, specifically that the signal voltage from the exhaust pressure sensor “A” is too low. This code is primarily associated with vehicles equipped with turbocharged engines, where accurate exhaust pressure readings are critical for optimal performance and emissions control. When this code is …
The P20CD trouble code is a diagnostic trouble code (DTC) that indicates a problem with the exhaust aftertreatment fuel injector “A” control circuit. This code is primarily associated with diesel engines equipped with selective catalytic reduction (SCR) systems. The SCR system is designed to reduce nitrogen oxide (NOx) emissions by injecting diesel exhaust fluid (DEF) …
